Powershell: Reading Messages from MSMQ

I'm throwing this out there since I couldn't find anything good online. We have admins that need to quickly look at messages in queues and the built-in tooling just isn't pretty to look at. Slap this PS code into a script file and you should be ready to rock!

param([string]$qname)

if ( [System.String]::IsNullOrEmpty($qname) )
{
    write-host "You must provide a queue name"
    exit
}

[Reflection.Assembly]::LoadWithPartialName("System.Messaging") | out-null

$q = new-object System.Messaging.MessageQueue($qname)

$msgs = $q.GetAllMessages()

foreach ( $msg in $msgs )
{
    $msg.BodyStream.Position = 0
    $sr = new-object System.IO.StreamReader( $msg.BodyStream )
    $sr.ReadToEnd()
    $input = read-host -prompt "Enter n for the next message, q to quit"
    
    if ( $input -eq "q" )
    {
        exit
    }
}
